Which one of the following is true ?a)An adult heart beats 70-72 times...
Understanding Adult Heart Rate
The correct answer is option 'A', which states that an adult heart beats 70-72 times per minute. Let's explore why this is true.
Normal Heart Rate
- The average resting heart rate for adults typically ranges from 60 to 100 beats per minute.
- A heart rate of 70-72 beats per minute is considered normal and healthy.
Factors Influencing Heart Rate
- Age: Younger individuals may have a higher resting heart rate.
- Fitness Level: Athletes often have lower resting heart rates due to efficient cardiovascular systems.
- Activity Level: Physical activity and stress can temporarily increase heart rate.
Why Other Options Are Incorrect
- Leg and Nervous System: The leg is a part of the musculoskeletal system, not the nervous system.
- Number of Bones: An adult human body typically has 206 bones, not 600.
- Nose Holes: The human nose has two nostrils, not one hole. These nostrils help with breathing and smelling.
Conclusion
Understanding heart rate is essential for assessing overall health. The normal range of 70-72 beats per minute is a good indicator of a functioning cardiovascular system, making option 'A' the correct choice.
